I looking for a recommendation for rear ceiling speakers on a 5.1 setup, which will only be used to watch movies. I don't put a lot of weight on the rear speakers and therefore don't care to spend much on them, unless otherwise warranted. I'm leaning on purchasing the Polk RC80i, which are $140 for the pair. I will spend more is someone has a better recommendation, but don't want to spend more than $200.
